2018-01-25soc/intel/cannonlake: enable pch link in bootblockCaveh Jalali
This moves the call to pch_enable_lpc() from romstage to bootblock. In other words, it happens earlier in the boot process. Turns out, we need this to talk to the EC to determine if we're in recovery mode or not. BUG=b:69011806 TEST=boots to linux Change-Id: I899bf343d705fe19a2978917bc88990495ebb5a3 Signed-off-by: Caveh Jalali <caveh@google.com> Reviewed-on: https://review.coreboot.org/23401 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
2018-01-16soc/intel/cannonlake: Program DMI PCR settingsLijian Zhao
According to CNL PCH BIOS spec (570374) 2.4.1, DMI cycle decoding needs to be programmed before it gets locked. Update lpc programming to add decode programming on DMI side as well. Also enabled io port 0x200 decoding by default. BUG=b.70765863 TEST=Apply changes and add chromeos EC decoding in mainboard devicetree.cb, then read back IO port in depthcharge cli and check that return is not zero.

2018-01-10soc/intel/cannonlake: Add a call to gspi_early_bar_init in bootblockFurquan Shaikh
This change adds a call to gspi_early_bar_init in bootblock to allocate a temporary BAR for any GSPI buses that are accessed before resource allocation is done in ramstage.

2018-01-05soc/intel/cannonlake: Correct PMC/GPIO routing informationLijian Zhao
PMC and GPIO DWx definition is not identical, hence update that to correct information. For cannonlake lp PCH, GPIO group C, group E and group GPD is different for PMC GPIO_CFG and GPIO MISCCFG. Also add function call to set up GPE routing in bootblock stage. TEST=Boot up into OS, and manually check PMC GPE status Change-Id: I1edb83edabc72e8a762b129cf51dcd936cd37ddf Signed-off-by: Lijian Zhao <lijian.zhao@intel.com> Reviewed-on: https://review.coreboot.org/22908 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Nick Vaccaro <nvaccaro@google.com>
2017-10-19soc/intel/cannonlake: Fix HECI error on resetLijian Zhao
Move HECI init from bootblock to romstage, the HECI bar saved by CAR_GLOBAL, which will be lost on different stage. HECI BAR in ramstage will be read back from PCI. Also add fail safe option to reset in case of HECI command not successful. TEST= Force global reset from FSP and read back HECI bar in debug print.

2017-10-18soc/intel/cannonlake: Use EBDA area to store cbmem_top addressSubrata Banik
This patch uses BIOS EBDA area to store relevent details like cbmem top during romstage after MRC init is done. Also provide provision to use the same EBDA data across various stages without reexecuting memory map algorithm. BRANCH=none BUG=b:63974384 TEST=Ensures HW based memmap algorithm is executing once in romstage and store required data into EBDA for other stage to avoid redundant calculation and get cbmem_top start from EBDA area.
